AJAX Example code showing XML response in a DIV tag

This is an example code which demonstrates how we can show the response from a XML file to the DIV tag.

<title>Using responseText with innerHTML</title>
<script type="text/javascript">
var xmlHttp;
function createXMLHttpRequest() {
    if (window.ActiveXObject) {
        xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
    else if (window.XMLHttpRequest) {
        xmlHttp = new XMLHttpRequest();
function startRequest() {
    xmlHttp.onreadystatechange = handleStateChange;
    xmlHttp.open("GET", "response.xml", true);
function handleStateChange() {
    if(xmlHttp.readyState == 4) {
        if(xmlHttp.status == 200) {
            document.getElementById("results").innerHTML = xmlHttp.responseText;
    <form action="#">
        <input type="button" value="Search"
    <div id="results"></div>

Notice the line in Javascript.

document.getElementById("results").innerHTML = xmlHttp.responseText;

This is doing all the magic for you.

Below are the contents of reponse.xml

<table border="1">
            <th>My Name</th>

Keep both the files in the same directory on server and run it.
